VMS, all of the Unix clones, RT-11 to name a few still provide full
development environment. I'm sure some(I would) here would add CPM
OS9 and even PC based DOS(MS, DRdos, CCPM...). the amount of freeware
or lowcost shareware for DOS/winders is quite impressive and plentyful.
Of all the software out there CPM-80, APPLE and PCdos has the largest
archives, but the PDP-8, -11, VAX archives are getting big.

Polymorphic originally called it the "Micro Altair" until MITS threatened to

Say Huh?
The Poly-88 was not an Altair. It was made by a group

I talked to a guy that does 7900A repair today. He said from what I
described that the heads are probably just in need of strong cleaning with a
toothbrush, then touchup with 100% alcohol. As long as the gimbal isn't
bent, all should be well. That takes care of the heads.
Then you wrote...

He also said the platter scapes make the platter almost, but not quite,
useless; and that I definitely need a new platter. The lower platter on the
7900A does in fact seat on a machined area of the spindle and doesn't need
special centering - "just bolt it on? - just bolt it on". He said I could
use any 14" disk media that was the right thickness. Can't remember if it
was 50 mils or 75 mils. I think it's the same as the RK05. I'll find out the
mils number tonight when I compare my 7900 cartridge with my 7905/6 one. All
I need to do is clamp a metal micrometer on the platter <just kidding
folks!>.
So - does anyone have a broken RK05 type cartridge that they'd part with so
I can steal the platter out of it?
>It's worth trying. Clean the platter as well. It can't do _more_ damage,

True, but if there is so much scraped oxide that the badtrack list is 10% of
the platter, why even bother.
I've been quoted anywhere from $50.00 to $250.00 for a media only surface
(no hub, which is all I need). Hopefully someone here can help out?

OpenVMS still comes with development tools. You can write
primitive interpretive code using DCL and more sophisticated stuff with TPU.
The file management system RMS also comes free with VMS.
Besides the above, there are many shareware or freeware
development tools that can be used with VMS. For the private user, VMS can
be free and comes with free C/C++, BASIC, Fortran, Perl and other compilers.
How does BeOS compare with that?

The only problem with that, Kai, is that some of the PC keyboards are

Well, the saga continues. This unit does have the 85 key keyboard and the
Sol-20 power supply so I don't know what to say about the model 10 on the
nameplate.
I took the keyboard apart last night and found both the sponge
disintegrating and the metalized plastic that contacts the keyboard also has
the metalization disappearing. Since I believe this is a capacitive type of
keyboard, I can see why it didn't work. What have others on the list done to
replace the plastic/sponge sandwich on this type of keyboard?
Yesterday, I spent all day at a customer's site, arguing with Windows NT.
God, I hate NT.
Anyway, I return to the office to clock out, call home, my mother answers.
I says, "Is my supper still there?" She says, "Yes, and hurry home, me
and your (little) sister went dumpster diving."
"Uh, WHAT?"
So, I go home. They scored 2 dead monitors, some miscellaneous System/36
disks, and 2 leased-line modems. So, I head out with them, to visit the
dumpster again. Turns out it was a grade school not too far away. Anyway,
I took some goodies, here's the highlights:
An Apple 2/E, in (seemingly) working order, but no floppy controller.
But it has the drives...
A Laser 128. No power supply. What's this?
IBM System/36 SSP and Microcode disks. Ohhh, yes.
The 2 leased-line modems - a small Gandalf model, and something else.
Miscellaneous 2e manuals. I have DOS disks and such elsewhere...
Anyway, what's the Laser, and can I do much with the Apple, even though it has
no floppy card? I suppose I have to RTFM...

That was my point, Hans. I can't comment on the Morris Minor, but the Yugo
did work, just as the Altair did. It's just that you always had to nurse
the Altair along. Now the IMSAI was a different thing. It was laid out by
a professional who designed the PCB assemblies like a "real" product, even
back when people thought of microcomputers as fancy "toys" for the
intellectual elite. The Altairs of the mid '70's were laid out the way 2nd
year engineering students did it. If they had hired a professional, it
would have cost more. Likewise, the Yugo was designed and built with many
economies in the form of omissions.

Hi!
I need the following stuff to fix my old TRS-80. I had it working again
after I dropped paper clips into it, but the person who was junking the
parts that I used to repair it were obviously throwing them out for a
reason...
I think all that I need are a model 3 or 4 motherboard, and a matching
RS-232 interface. I could also probably use a model 4 keyboard, if I get
the model 4 motherboard, but the model 3 one will still work, won't it?
I also need a disk copy of VideoText software, Scripsit, and TRS-DOS (I have
L-DOS, but it's for the Model 4).

In my rush to spin up the drive, I had neglected to inspect the bottom heads
for the fixed platter. They are, after all, almost hidden in the bottom. :[
This time I removed the bottom of the drive and looked underneath. There are
the obvious telltale streaks on the bottom surface of the bottom (fixed)
platter; it doesn't look gouged, but streaked nontheless. The bottom heads
(which can only really be inspected from the bottom of the drive with the
bottom cover off) don't look to be very happy. Definite oxide residue, but
the heads at least LOOK structurally sound.
Since the bottom fixed platter doesn't have servo data on it, I'm hoping a
new bottom platter won't cost much more than a removable platter. Then I'm
hoping that since the noise was never that pronounced that perhaps the heads
will be OK after thorough cleaning. Don't know much about this - is that
possible? I know, I'm probably hoping unrealistically.
This pretty well trashes my hopes for TSB, at least until I can fix it or
find another 7900A. On the bright side, it's pretty obvious that this damage
was done before I got the drive. Small consolation ;)

Hi!
I just found an old Motorola Universal Data Systems model 201B/C modem in my
basement while I was cleaning. I have the original box and manual, but
can't figure out how to get it to work.
It's odd- looking (in the fact that it's blue).
It runs on 120 volts, has a 1/2 amp fuse, a toggle (power) switch, 25-pin
DTE data connector, and the telephone input/output connectors on the back.
The front is black and has 9 LED's on it, along with a rotary switch. The
LED's are (left to right) MR/RI, TR,RS,CS,CD,RD,TD,TM,and POWER. The rotary
switch (which is between the "TM" and "POWER" LED's has 9 positions for
RDLST, RDL, LDL, AL, DATA, TALK, TTP, RTP, and ST. According to the manual,
these are different test settings.
Anyone ever worked with one of these?

the only compatibility issue i had with the laser was that it wouldnt work

laser claimed 99% just for these type issues. It's my understanding that the
laser128 had the universal disk controller builtin so it handled pretty much

I've gotten my hands on a touchscreen GRiDpad. I don't recall the
model number, but its just an LCD panel with some buttons along the side,
and a stylus. I found a keyboard port pinout for it and build a power
adapter, and can get it to ask me to abort, retry, or fail, but I cannot
get it to do anything remotely useful.
The appeal of this system is that I am a religious GEOS user for
MSDOS pc's, and the idea of having touchscreen-GEOS is pretty cool (GEOS
has built in support for the GRiD's goofy video resolution, I believe, as
well as support for its touchscreen-mouse driver).
My question is this: What do I put on a hard drive to get it to
boot? It seems reluctant to boot off of a conventional micro-IDE drive
that has MS-DOS on it, and if I don't have a drive plugged in it says GRiD
Bios v. something.something.
When I first got it it had no HD in it at all, just two PCMCIA
looking slots, which I would assume to be PCMCIA sockets. One of these
sockets is on a daughter board adjacent to a micro-IDE connector. I am
stuck. I've had this in my basement for quite some time, but I can't
figure out how to get it to boot anything.
On a side note, I've also picked up a 1958 Tektronix O-scope (the
school I go to was tossing it). It works fine, aside from the fact that
the CRT on it scans so far to the left as to be almost off the screen.
Does anyone out there have experience with this vintage of oscilloscope?
Thanks!

I'm in need of sage advice from others on the list, due to my lack of
troubleshooting/repair experience with large (14") hard drives. I'm a
sophomore with electronics, but these beasties are largely mechanical and
out of my meager knowledge set.
Background:
I finally got a brand new (yes, really brand new) blank disk cartridge for
my HP 7900A disk drive. The drive has never been powered up since I got it.
The spindle motor won't even start on these drives unless the cartridge is
in place (there is also a fixed platter underneath). Since the drive is
obviously not checked out, I wanted to get blank media to test so I didn't
ruin valuable data on a cartridge I am getting later. First I very
thoroughly cleaned the drive inside and out, cleaned all contacts, heads,
positioner reticule, etc. etc. etc. I then checked the power supply out
carefully. Then I powered up the drive (without the cartridge) and tested a
number of the basic mechanical functions, interlocks, and test points on
some of the cards called out by the operating manual. Then I wanted to try
loading the cartridge to see if the heads would crash nicely :) Keep in mind
that once the cartridge is in, there is a load switch that powers up the
spindle and 30 seconds later the heads do a seek. At any time during the
spin up or seek, the unload switch will immediately and very quickly retract
the heads and then the drive spins down.
"Problem":
I put the cartridge in the drive and hit load. You can hear the spindle come
up to speed. Exactly 30 seconds later as stated in the operators guide, you
can hear the heads move and then the drive ready light comes on. From what I
understand if there are any problems at all up to this point, the drive
fault lite would come on (including a seek fail, etc.). I kept my finger on
the unload switch. The second the heads came out I could hear a
disconcerting noise. I immediately hit unload. I removed the cartridge, and
inspected both the cartridge and heads carefully. No obvious signs of
problems. I reloaded the cartridge. This time, when drive ready lit up, the
drive was nice and quiet for about 25 seconds. Then I started hearing the
noise again. On and off, more and more, so I hit unload. Rechecked the heads
and cartridge again - no obvious signs of damage. Tried loading the
cartridge again. This time it ran for a few minutes before I heard the
noise. I unloaded and rechecked everything, still no signs of problems.
Gee - can you tell I'm paranoid about possibly ruining the new cartridge
and/or the heads? :)
The sound is not quite metallic, but very close. It sounds like something
rubbing at high speed but at a pretty high pitch. The best way I can
describe it is that it is almost identical to the sound an 8" floppy disk
makes when you put it into an RX02 drive and close the door (the media
turning inside the sleeve), but much louder. I'm pretty uncomfortable
proceding with diagnostics, etc. unless someone here can calm my fears as to
what the sound might be. Is it just due to the fact that it's a brand new
cartridge, or is it indicative of a potential head crash, just a belt issue,
dust, etc? I'm pretty familiar with the whine a drive makes when the
bearings are going out, and it does not sound like that sound.
Any help, ideas, thoughts, etc. are MOST appreciated!

No, there was never really a Sol-10. The Sol-10 was just a Sol-20 without
the disk controller or something like that. If yours says Model 10 then
that's interesting, and Bob Marsh lied :) Maybe it was the one that

Hi all,
today some quite unbelievable piece of luck happened to me:
While I was walking by the back entrance of a smaller University
here in Minneapolis purely accidentally, not thinking about computers at all,
I ran into
a pile of electronics. Short investigation revealed that it was a 1965 CDC
3000
series hard drive electronics cage (14" removable pack electronics),
perfectly undamaged and complete with all the ~150 cards (it so happened that
I worked on an identical cage about 15 years ago),
plus a heap of cards from assorted ~1971 Univac / Burroughs machines !
Within the next hour I found out that the building will be completely
remodeled,
and had to be emptied out. Quite obviously, someone forgot about 25 years ago
this set of things in the second-level basement; nothing else there, though.
General lesson: we should ask all schools regularly for their renovation
projects !!
John G. Zabolitzky
P.S. If anyone knows about / wants to get rid of CDC equipment of that
vintage, please let me know !
And yet another one... An Intel MCS-85 System Design Kit (8085
based single Board Computer) has wandered in sans docs...
Anyone have a manual on this critter?

I recently got a couple of tape streamers: a Tandberg 3610 and
a 3300. Does anyone have any documentation/specs on these drives?
Cheers,

To answer Tony's question first, yes you can. Take one of each belt and turn
them inside out, i.e. teeth on the outside. (.080 inch from HP-85, .081 inch
>from can't remember the make of papertape punch that was sold in the UK by
Teleprinter Equipment.) Try and mesh the teeth of the two belts. It soon
becomes obvious which one has the larger pitch. These belts, being
string-reinforced, are not very stretchy and it would be difficult to get a .080
to run on .081 pulleys.

It might be a solution. In my Tektronix 4662 the belt is intact, but the pulley
has died (20 teeth) I glued the old bits of (plastic) sprocket to the (metal)
hub but it was just inaccurate enough to drop a tooth here and there. Result,
the plotter couldn't get at the pens because they were offered up to the pen
carrier at the wrong place...
It might be quite easy to _buy_ new sprockets for .080 pitch. If not, I may ask
to borrow your lathe, dividing head, etc...

Lucky you. When I contacted Stock Drive Products, they referred me to their UK
agent, Davall. Davall do not, as far as I can determine, stock the HP85 belts.
I found, eventually, another supplier, who said they could get the .080 and .081
pitch belts. I told them what belts I wanted and they promised to fax me a
price, but I never heard any more. When I next get around to looking at the
punch, I'll have another try...

Out on another info quest...
Just added a couple of Kennedy 9610, 9-track tape drives to the collection
(nice since they are multi-density 800 thru 6260) and of course have no
docs on them... (ain't it always the way?)
So in particular, I'd like to find some tech info on the (so called)
"Pertec Interface" so I can figure out what various systems in the
collection I might be able to convince these critters to work with. (and
get a bit more knowledge on tape drive interfacing in general)
Any assistance, pointers, spare docs, etc., most welcome!
Thanks;

Hi. I'm from Portugal, and I just wanted to state my interest
on old computing material (non-PC) anyone wants to

I believe I have located the appropriate materials to allow me to
sysgen my 11/44 RSTS/E system, in order to add support for RL02s,and
maybe RX02s and a few other things....
I have obviously never essayed this task before, though I *have*
sysgenned a number of smaller CP/M systems, and I think I understand
the basics of what/why.
If there is anyone on The List reading this who has done this
(sysgenning RSTS) before, and *especially* if there are big gaping
booby traps to fall into... I would be most interested in the
benefit of your experience.
The install.log is available from the previous sysgen, so I have
all the responses to the dialogs.
Like (duh!) ought I to back up what I have now? [how does one do
this to MS0: 1/2" tape?]
Ought I to partition the drive? Does the process overlay the
existing OS areas, or does it start over completely?
And please don't jam me about RTFM... even if I *had* them I'm sure
I'd have a bunch of other newbie questions....
;}
Cheers and thanks...

Hi folks,
I was just lucky enough to acquire a PT SOL-20 (1976) in great shape to add
to my collection.
Unfortunately, no documentation, I would dearly love to have that, either in
the original or a photocopy
Anybody??
Thanks

While we're on the subject of decaying rubber in an HP85, I would add, don't try
to run the printer until you have opened the unit up and freed off the drive
belts - one for paper advance, one for print head. These belts go sticky and
stick to the pulleys, so that when you try and run the machine they tear
themselves to bits.
It's a pity you weren't here a few months ago - a number of us got together and
bought a bulk order of replacement belts very cheaply. I still have a spare
pair if you're desperate, and I imagine one or two others may.
FWIW the teeth on these belts are pitched at 0.080 inch - the standard "mini
pitch", unlike some equipment I have which uses belts with the teeth at 0.081
inch...
Philip.

Hi all,
I'm working on a volunteer project at the Computer History Center to
interface a Documation desk top 80-column card reader to an IBM PC. The
card reader is in very good condition, however we have no documentation
for it. Do you know of, have, or can you provide pointers to any
documentation
for this device, how to interface to it, or operational information?
On the back panel of the reader is a plate which lists the model as
Documation "Model RM/TRM 10.12L-10.12C", with a sticker on the front
with "Model 10.L12+", and operates at 115V 6.1A.
The reader has a 1" x 2" (approximately) data connector on the back with
this layout:
+---------------------+
| O O O O |
| O O O O |
| O O O O O O |
| O O O O |
+ | O X O | +
| O O O O |
| O O O O O O |
| O O O O |
| O O O O |
+---------------------+
Legend: O female connector
X Connector screw hole in center of the recepticle
+ Guide holes where the hood would attach
The data connector is similar to, but isn't, a V.35 connector.
TIA for your help. Please respond via email or phone.
Thanks!

Hi folks,
I went to the Rochester Hamfest on 5 June. Amongst other radio and computer
items I dragged home were two VXT2000 boxes. No displays or keyboards, just
the pizza boxes. The guy literally gave them to me when I was at his
fleamarket space as he was starting to packup and go home just because I
was studying them intently (I never saw one before).
That'll learn me not to stare so dang long at somethin' an' get nabbed by
the owner! My wife was there too. She just rolled her eyes after the
'transaction'. At least she carried the NOS P54 motherboard and parts we
found for my stepson's computer upgrade plus some radio parts and manuals
after I got handed the VXT's.
These I understand are X-terminals but I know nothing else about them.
Searching the usual places for useful info only told me they were X-terms.
Could anybody provide more info to a curious mind as to what the hardware
details are, their typical usage, any other details, etc.? Specific model
numbers are VX20A-AA and VX20A-BC. I see the -AA has color video output and
the -BC is monochrome. Seem to be the only hardware diffs.
Will the good old LK201 keyboard work with these? What about the mono
video: will the VT240 mono monitor work with the -BC?
Kinda classy-lookin' hardware inside. Useful for anything (seriously)?
Off-list please as these are really less than 10 years old.
Thanks in advance for your usual good info!
Regards, Chris

Hi Erik:
Thanks for the email. You'll need the Processor Handbook for the 11/70. It
tells all about how to use the front panel. If you need schematics
(probably not at this stage) then I can assist. I don't have the processor
handbook, I suggest that you post on the classiccmp list and one of
several people (Tony, Megan, Allison, Tim, ...) will likely respond with
an offer to photocopy the relevant sections.
I run a pdp-8 web site, one friend runs a pdp-11 web site on my machine.
He may have posted the 11/70 manual in scanned form, or may have it and be
able to scan it/copy it for you. Check out
http://highgate.comm.sfu.ca/~rcini.
Good luck,
Kevin

Very nice X-Terminal. Even fast. Just got one of these one month ago and
love to have it on my DECStation/NetBSD.

The VXT2000 is a little brother of the VAXStation 4000/90 (got the SGEC
EThernet Chip form there) and the VAXStation 4000/vlc (got the CPU from
there. Same CPU & Clock)

You can use the "standard" ps/2 simms in it. but only the 4MB pieces.

Yes.

NO, look at the resolution above :-((

YES. As a X-Terminal.

<Okay Allison, now you caught me with three heretofore unheard of terms:
<Cvax, Nvax and SOC. What the heck are these definitions? My MVII: what ter
<above applies to it?
Microvaxen are all the same like 386, 486, P5, however they mostly differin
technology used to make them.
MVII is the first NMOS version.
Cvax is a CMOS version that was about 2.4-3.0 faster.
SOC is system on chip, more of the glue and larger cache are inside it.
speed on this can run to greater tha 20x MVII.
Nvax is Cvax with internal cache 3-8x MVII
I listed them in order of speed.

<I can pick up a VAXstation 3100 (just the box, no monitor/keyboard/etc).
<Is this worth messing with?
Yes for OSs there are three choices, VMS, Ultrix and NetBSD. There is a
free license for the first one and the last one is not quite ready for
prime time(unless you really like to work at it).
<What's in it processor wise?
Vax! Without a specific model number it's hard to be more specific.
They are all VAX, the difference being speed and added performance.
Of it's an older one it's like Cvax, later Nvax, most recent SOC.
Most 3100s are SCSI for disks and tape, have eithernet and several serial
ports so they can be quite useful for routers, mailservers, WWW servers and
the like.
< Can I rig it to a VGA monitor?
Never tried, uses some high scan rates and very high resolution.
However if that fails you can plug a terminal into the back and
talk to it that way.
<Should I let it pass?
I'm biased, never!

That's OK - any DEC reseller will be glad to sell you something like a
DECServer 700. Looking through the _Processor_ that came in the mail
today I see some 16-port units with flash memory in the $1500-$2000
price range. They're *nice* terminal servers - you can even set them
up as either end of a PPP connection and they'll route to/from your
LAN!

<I assume the SCSI cable required is the old style 68? pin (female)
Yes the M76 requires the 68pin at one end cable.
Also JDR (WWW.JDR.COM) in California has 4x SCSI cdroms for a cheap $29.95
This might help others looking for SCSI cdroms. Don't know if that would
work right with vaxen but it's cheap.

See if your version of Linux supports Digiboards. If so I have a bunch but I
will need time to make a list. They are 2, 4, 8 and 16 port version and the 8
and 16 port ones that I have played with so far you can run with either no
interrupts under NT4. I only have a few cab kits however so you may have to
make a cable set. I think I have the pinout info.
Contact me off list for further details.
